Description

Technical Field

[0001] The present invention relates to the technical field of sanitary pest control, and in particular to a synthesis method of low-energy consumption mouse glue and the mouse glue. Background Art

[0002] When killing rats, you need to use a rat-killing board. The sticky rat board is the most commonly used tool in the physical control method of rats. Its sticking effect directly depends on the colloid properties.

[0003] The formula of mouse glue in the existing technology usually contains butyl rubber. Due to its excellent weather resistance and viscosity, butyl rubber has become the preferred base material for high-end mouse glue. For example, Chinese patent No. CN103497711A discloses a mouse glue and its preparation method. The method comprises: BASF polyisobutylene B150 and butyl rubber 1751 from Germany are crushed in a kneader and added to a reactor. After heating and dissolving cyclopentane oil, a UV inhibitor, an antioxidant, polyethylene, aluminum stearate, and disproportionated rosin resin KA100W are added. After all the above ingredients are dissolved, polyisobutylene 1300 is added and dissolved into a whole.

[0004] However, the insolubility of butyl rubber seriously restricts production efficiency. Energy consumption in the dissolution stage accounts for more than 40% of the production cost, and the entire process takes more than 6 hours, which limits production capacity expansion. High temperature will also cause degradation of raw materials. Even if antioxidants are added, the degradation of the material cannot be completely avoided, affecting the performance and life of the colloid.

[0005] In general, the production process of currently available mousetrap glue is long, resulting in high energy consumption and increased production costs. This also hinders production scheduling and quality improvement, and negatively impacts quality stability. Therefore, developing a low-temperature, fast-dissolving butyl rubber production and synthesis process is of great importance to reducing mousetrap production costs and improving product competitiveness. Summary of the Invention

[0006] The invention aims to provide a mouse glue having simple method, low equipment investment, low energy consumption, stable product quality and short production preparation time, as well as a synthesis method thereof.

[0007] In one aspect, the present invention provides a method for synthesizing low-energy mouse glue, comprising the following steps: (1) adding 4% to 7% by mass of butyl rubber and 1.5 to 2.5 times the mass of the butyl rubber in n-hexane into a reaction vessel; (2) stirring at normal pressure and temperature to dissolve the butyl rubber; (3) adding rubber oil in an amount of 4 to 5 times the mass of the butyl rubber to the solution obtained in step (2), continuing stirring, and recovering and removing the n-hexane through a reflux condenser; (4) heating the system to 120°C to 130°C, adding a tackifying resin and a stabilizer, and continuing stirring under normal pressure; wherein the amount of the tackifying resin added is 10% to 13% of the total mass of the mouse glue formula, and the amount of the stabilizer added is 2% to 5% of the total mass of the mouse glue formula; (5) adding liquid polybutene, antioxidant and remaining rubber oil, stirring and discharging; wherein the amount of liquid polybutene added is 30% to 40% of the total mass of the mouse glue formula, the amount of antioxidant added is 0.5% of the total mass of the mouse glue formula, and the total amount of rubber oil added is 35% to 45% of the total mass of the mouse glue formula.

[0008] Preferably, the stirring conditions in step (2) are: stirring for 1 to 3 hours at normal pressure, normal temperature, and a stirring blade speed of 34 to 36 r / min, so as to increase the dissolution rate of butyl rubber.

[0009] Preferably, the stirring conditions in step (3) are: stirring for 1 to 2 hours at normal pressure, a temperature of 50°C to 60°C, and a stirring blade speed of 34 to 36 r / min to increase the removal rate of n-hexane.

[0010] Preferably, in step (4), the system is heated to 120°C to 130°C for 1.5 to 2.5 hours, and then stirred at normal pressure for 1.5 to 2.5 hours. The temperature is slowly increased over 1.5 to 2.5 hours to prevent local overheating, which could cause aging and degradation of materials in the gelling kettle. This reduces costs while ensuring product quality.

[0011] Preferably, the antioxidant is AT10, which can still maintain activity in the high temperature range of 120-130°C.

[0012] Preferably, the recovery rate of n-hexane in step (3) is ≥98%. Recycling n-hexane reduces production costs and also prevents n-hexane from adversely affecting the properties of the rubber compound.

[0013] Preferably, the butyl rubber in step (1) is cut into multiple rubber strips to increase the specific surface area and further shorten the dissolution time.

[0014] Preferably, the tackifying resin is C5 hydrogenated petroleum resin, which matches the solubility parameters of butyl rubber and has good low-temperature compatibility. The selection of hydrogenated tackifying resin can improve the overall performance of the rubber compound, improve the aging resistance of the product, and extend the shelf life.

[0015] Preferably, the stabilizer is polyethylene, which is inexpensive and has a stable source, can improve the product's anti-flow performance, and greatly enriches the product's placement and usage locations.

[0016] On the other hand, the present invention also provides a mouse glue, which is prepared by the synthesis method according to any one of claims 1 to 9 using the following components in the following mass percentages: Butyl rubber: 4% to 7%, Liquid polybutene: 30% ~ 40%, Rubber oil: 35% to 45%, Tackifying resin: 10% to 13%, Stabilizer: 2% to 5%, Antioxidant: 0.5%.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. Dissolve butyl rubber at room temperature, reducing energy consumption.

[0018] 2. Remove n-hexane (its boiling point is 69°C) at a low temperature of 50 to 60°C to avoid high-temperature cracking by-products.

[0019] 3. Add tackifying resin (step 4) and liquid polybutene (step 5) in sections, ensuring thorough mixing.

[0020] 4. The present invention uses low-temperature dissolution + solvent recovery process as the core, which is different from the existing method that relies on mechanical crushing and high-temperature dissolution of cycloparaffin oil. It combines the timed addition of components, targeted material selection and refinement of process parameters to achieve a technological leap from "high energy consumption and long cycle" to "low carbon and high efficiency" in the production of mouse glue.
